To all whom it may ,comcerjn B it known ha i n lulA ag h iwAl a J12, ,a citizen of;the ;U;nited .States,v and a resident. of the borough of .Manhattan, city, county, andStateof New York, haye invented 1 W an u f llmprovemenls .in Wafers, as hereinafter set forth.

-This invention is ,an improvement in st e on p pe faste r its ,objec is t produc r heap and simp ar i of? ma ufact r s ingep ra pap rs. 1 together, and -for other .s 1m 1lar .p11rposes,..

with both sides either partly ,or ,wholly; coated-with gum or solvenhadhesive ma-i terial, sothat itis capahle ofbeing inter- 20 posed between the,mount,and the print, with its opposite; faces adhering to the, proximate faces ofeach, thus securing thotwo together, and providing a satisfactory substitute for. .the pastingpirocess usually; employed, and which willhold; the print; flat so; thatwarp-v ing of the ,mount will not take place and also so that the. print can be remoy ed from, the mount whenever desired without injury to either. These qualities are-obtained by the 30.:formation. of thewafer with,two se,paratd uim.-coatedv portions or sides united at their: lateral edges so as; to-be-capalnle f relative movement when necessary, after the man ner ofa bellows, which thus permits of sufli cientrelativemotion between theprint and the mount to avoid wrinkling of; the former and. warpin-gnf the latter, thedifi'erences in the shrinkageand expansion of the two; be ing accommodated by the fle tibility of the 40 wafers. The use oi littleor no moisture in [the affixing of the print,, also .tends to ayoid the tendency of the-mount .to warp. The .desired extentof such,relativemotion between the two, gummed port ions of,. each 4.5 wafer is-determined by the relatiye area of each sideof the ,wafer thatis'coyered .by the gum, the latter being preferably, though not necessarily, ,applied to. {the central. ,part, ,of cach face,v leavin an. uncoated .,1nargin on so. each side which nce does hotadhere to either-the mountnn the ,print and isther fore free to flex in self-adwstment aQQQ rding to the. condition of. the strains. s-Such a wafer, coated. as described and. fprnqeclpt ,fine, tough paper or.tissue, normally holds the print fiatjagainst the mount in quite the .sa nqposition as if pasted. thereon, and also ,providcsa quick and easy method of removingthc, print, since the uncoated portion of ,each ,wafer can be flexed outwardly and then cut or torn to separate the two gummed portions .of the wafers, thus releasing the print without damaging it or the mount, the ,amount of wafer, left adhering to the mount being, negligible.

In the drawingsforming a part hereof, lif igurel is a fragmental perspective view of a card mount on which a sheet of paper is secured hy means. of four wafers according to my, invention, the view. being- .in section .through two of. the wafersyFig. 2 .is a per spective yiew of one o v the wafers, showing alsothe,preliminary stagcsof one of the .gnethods of its manufacture; Fig. 3 is an enlarged end view of a section of the tube illustrated in- Fig. 2 and of two of thewafers before they arecollapsed or flattcned Fig. i. reprcsentsnnothcr and simpler method of manufacture; Fig.- 5 a perspective view of the noclified iorm, ofgwafcr produced therey; and Fig. 6 a section of. the same in use ,loctween a cardboard anda print.

The wafers lconsist ofa tubular section of ,tissue or other thin pliable male rial,. which iscollapsed or, flattened to form a suhstantially. flat wafer, and provided on ,each side with a coating; 5, of .gum. or glue, so applied, that it coreisa portion only of each side of ,the wafer, extending longitudinally. from. mid. .to end 'fliereof and preferably sons to formwcl. defined; lines of separation between the ,gummed and. un ,g lllllflleil parts. 'ljhcgum is preferably applied to each side of the wafer, so that each adhesive strip extends along the iddlc portion of the .wafer and is locate d at qual distances, from its lateral edges, so thzi the uncoated, margins. 6--(5 are of equal width, and the two strips of gum on each wafer are ..thus locatedgdu'ectly opposite to each other.

,The wafer 7 shown in. Fig. 5 consists of a flat strip with its ends folded over. toward and substantially. meeting eaclrpther, though not necessarily overlapping, as in the case of .wa er-4. A gum strip is applied to the exterior surface of thesrdeof the wafer that is formed by these proxirnateends, as indicated at, 8 and anqther.,g,mm strip 9, is,applicd to erahiy ie'i t ti efoie ii g to unite the iree tom Ior one to c the other.
